1917] Fernald,— A new Vitis from New England 145 
the green foliage of the latter, the leaf-contour nearly of the former, 
the tendrils and inflorescences often continuous (that is, several in 
succession before an interruption) as in V. rusca, the grapes large 
as in the latter species but with the clear acid flavor without “ muski- 
ness” as in V. vulpina. The seed of this grape is quite as large as in 
V. Labrusca but somewhat more slender. 
The disposition of this plant as a hybrid between V. vulpina and 
V. Labrusca has never been satisfactory to the present writer for the 
very practical reason that the intermediate vine occurs in great pro- 
fusion as a river-thicket vine, climbing high over the trees of the 
alluvial banks, in river valleys where no plants of either of the sup- 
posed parent have ever been detected. In Maine V. Labrusca is 
confined to the coastal strip eastward to Penobscot Bay (and there 
very rare and local), extending inland to the Saco and lower Andros- 
coggin Valleys. V. vulpina, on the other hand, is an extremely rare 
vine in Maine. It occurs from the mouth of the Aroostook River 
southward along the St. John in New Brunswick and is presumably 
found along the Aroostook River across the border in Maine. It is 
found in the valley of the Piscataquis (southeast of Moosehead Lake), 
in the valley of the Sandy River (southeast of the Rangely Lakes) 
and locally in the Androscoggin Valley and southward into York 
County. North of Maine it extends to Lake St. John and thence 
westward to the Rocky Mountains and it is broadly distributed from 
western New England southwestward. 
The intermediate vine, as demonstrated by careful botanizing in 
the valleys of the St. John, Penobscot, Kennebec and some of the 
minor rivers of Maine during the summer of 1916 by Mr. Long 
and the writer, is the characteristic grape-vine in alluvial thickets 
throughout central and west-central Maine where no V. Labrusca is 
found and where no V. vulpina has been observed. It is a locally 
abundant vine along the main Penobscot northward as far as northern 
Penobscot County, along the Kennebec northward nearly to Moose- 
head Lake, along the Androscoggin into Coés County, New Hampshire, 
where, I am informed by Dr. A. S. Pease, no V. Labrusca is known; 
and the Gray Herbarium and the herbarium of the New England 
Botanical Club show characteristic specimens from southwestern 
Maine and northeastern Massachusetts and from the Connecticut 
Valley of New Hampshire, Massachusetts, and northern Connecticut. 
Only in this latter valley and in the region from southern Maine
